"The powerful Webb telescope doesn't need to take pretty pictures to revolutionize our grasp of the cosmos," he said.

It's "a game changer". They're part of what the Webb telescope's web site calls "an international team numbering in the hundreds" that "independently analysed data from four of the Webb telescope's finely calibrated instrument modes." And their ground-breaking first results?

The James Webb Space Telescope "just scored another first: a molecular and chemical portrait of a distant world's skies."

While Webb and other space telescopes, including the NASA/ESA Hubble Space Telescope, have previously revealed isolated ingredients of this heated planet's atmosphere, the new readings provide a full menu of atoms, molecules, and even signs of active chemistry and clouds.... The telescope's array of highly sensitive instruments was trained on the atmosphere of WASP-39 b, a "hot Saturn" orbiting a star some 700 light-years away...

Earlier Mashable explained that the researchers "wait for planets to travel in front of their bright stars. This starlight passes through the exoplanet's atmosphere, then through space, and ultimately into instruments called spectrographs aboard Webb... essentially hi-tech prisms, which separate the light into a rainbow of colors. Here's the big trick: Certain molecules, like water, in the atmosphere absorb specific types, or colors, of light."

The findings bode well for the capability of Webb's instruments to conduct the broad range of investigations of exoplanets — planets around other stars — hoped for by the science community. That includes probing the atmospheres of smaller, rocky planets like those in the TRAPPIST-1 system.... Among the unprecedented revelations is the first detection in an exoplanet atmosphere of sulphur dioxide, a molecule produced from chemical reactions triggered by high-energy light from the planet's parent star.... "This is the first time we have seen concrete evidence of photochemistry — chemical reactions initiated by energetic stellar light — on exoplanets," he said

This led to another first: scientists applying computer models of photochemistry to data that require such physics to be fully explained. The resulting improvements in modelling will help build the technological know-how needed to interpret potential signs of habitability in the future.... The planet's proximity to its host star — eight times closer than Mercury is to our Sun — also makes it a laboratory for studying the effects of radiation from host stars on exoplanets. Better knowledge of the star-planet connection should bring a deeper understanding of how these processes affect the diversity of planets observed in the galaxy.

Other atmospheric constituents detected by the Webb telescope include sodium (Na), potassium (K), and water vapour (H2O), confirming previous space- and ground-based telescope observations as well as finding additional fingerprints of water, at these longer wavelengths, that haven't been seen before. Webb also saw carbon dioxide (CO2) at higher resolution, providing twice as much data as reported from its previous observations...

Imagine being so uninformed that you think that would be a productive use of telescope time. If dark matter is discovered it will be with cosmological experiments, high energy missions or particle experiments.

That has been seen a lot already, It doesn't tell you what dark matter is. It's also not definitive evidence as people can also claim that some modified gravity model could produce the lensing. There are lots of JWST observations of strong lensing galaxy clusters.

I understand the value of analyzing hot Jupiters and other gas giant exoplanets, but can they PLEASE just start looking at nearby terrestrial planets within the habitable zones of their stars? For the PR boost, if nothing else

>> No.15018917

>>15018610
People are working on it. Several Trappist-1 transits have been observed. But it is an immensely complicated instrument, with many different modes which can be used for transit spectroscopy. It takes time for the analysis and systematics to be understood.

What the fuck has to be "rewritten"??

Planets orbit stars
Some of those planets are gas giants
Some of those gas giants have photochemistry going on in their atmospheres.

We already knew all of this.
